Could not start RewriteMap program error
My VPS (CENTOS 6.9) stops working every two or three weeks. If I restart the server everything works again. Below are the last lines of the error log of last two crashes. What could be the cause?

Hello, [Tue Jan 09 02:01:54.848979 2018] [mpm_prefork:error] [pid 9826] (12)Cannot allocate memory: AH00159: fork: Unable to fork new process This is due to low memory. Please upgrade your vps memory. 0 -
Hello, It looks like your VPS is running out of memory. You can use the following command to get a better idea of how much memory is available: free -m
Outside of adding more RAM to the VPS, you may want to consider switching to a different MPM (prefork can sometimes result in higher memory usage): Multi-Processing Modules - MPMs - EasyApache 4 - cPanel Documentation Thank you.0 -
free -m
total used free shared buffers cached Mem: 1024 432 591 3 0 181 -/+ buffers/cache: 250 773 Isn't 40% used memory enough? It is always around this figure. When I try to get root access I often get error "cannot set user ID: resources temporarily unavailable". I then restart server to get root access.0 -
Hello, The usage looks okay there, but it's possible that it's increasing with more visitors. The following thread is intended for troubleshooting high load averages, but it also includes some information you can use to help determine the source of the resource usage: Thank you. 0 -
Thanks for your help. I changed MPM from prefork to worker. Ram usage is now down to 20%. 0 -
Too early, I got a server crash again. [Wed Jan 10 14:06:56.870373 2018] [mpm_worker:notice] [pid 1530:tid 140053110179808] AH00297: SIGUSR1 received.

Every crash seems to happen after graceful restart and leechprotect that cannot restart. Any more suggestions? Are the limits.conf settings ok?* soft core 0 * soft nofile 512 * hard nofile 1024 * soft nproc 2047 * hard nproc 16384 ftp hard nproc 00 -
Hello, Feel free to open a support ticket using the link in my signature so we can take a closer look at your system. Thank you. 0 -
I ended up with an upgrade, from 1GB to 2GB RAM. No problems so far. Is it normal that the VPS is running at the same % RAM as before, I would expect a usage drop of 50%. 0
