Hi, When I do strace in WHM for the mariadb process I get this output, indicating some errors. Can anyone help me out to ubderstand what this is. Did lots of searching on Google but got stuck. strace: Process 3201 attached restart_syscall(<... resuming interrupted read ...>) = 1 accept4(21, {sa_family=AF_UNIX}, [128->2], SOCK_CLOEXEC) = 742 futex(0x555c69c07e94, FUTEX_WAKE_OP_PRIVATE, 1, 1, 0x555c69c07e90, FUTEX_OP_SET<<28|0<<12|FUTEX_OP_CMP_GT<<24|0x1) = 1 accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=20, events=POLLIN}, {fd=21, events=POLLIN}], 2, -1) = 1 ([{fd=21, revents=POLLIN}]) accept4(21, {sa_family=AF_UNIX}, [128->2], SOCK_CLOEXEC) = 742 futex(0x555c69c07e94, FUTEX_WAKE_OP_PRIVATE, 1, 1, 0x555c69c07e90, FUTEX_OP_SET<<28|0<<12|FUTEX_OP_CMP_GT<<24|0x1) = 1 accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=20, events=POLLIN}, {fd=21, events=POLLIN}], 2, -1) = 1 ([{fd=21, revents=POLLIN}]) accept4(21, {sa_family=AF_UNIX}, [128->2], SOCK_CLOEXEC) = 742 futex(0x555c69c07e94, FUTEX_WAKE_OP_PRIVATE, 1, 1, 0x555c69c07e90, FUTEX_OP_SET<<28|0<<12|FUTEX_OP_CMP_GT<<24|0x1) = 1 accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) accept4(21, 0x7ffc091e6f20, [128], SOCK_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=20, events=POLLIN}, {fd=21, events=POLLIN}], 2, -1) = 1 ([{fd=21, revents=POLLIN}]) accept4(21, {sa_family=AF_UNIX}, [128->2], SOCK_CLOEXEC) = 742 futex(0x555c69c07e94, FUTEX_WAKE_OP_PRIVATE, 1, 1, 0x555c69c07e90, FUTEX_OP_SET<<28|0<<12|FUTEX_OP_CMP_GT<<24|0x1) = 1

    Hey there! My first question would be why are we looking at an strace of the database process? Is there some specific issue you're trying to track down that isn't showing up in the standard log files or process tracker? The output above doesn't necessarily indicate a problem. You can find more details on that here:

    Thanks for that confirmation - there's nothing wrong with being curious at all, but I'm glad there was no issue either!
