queueprocd fails with json parse error

gdimi
Hello to all, after some pool metadata failure and recovery, all seems ok but I discovered that queueprocd fails with some weird JSON data error here is the log output:

any ideas on which file may be corrupted? Thanx in advance, George

    ok I found it. I search for recently modified json files in /var/cpanel and /usr/local/cpanel/ and found that /var/cpanel/taskqueue/servers_sched.json was corrupted. So I nulled its contents and restarted queueprocd ( /usr/local/cpanel/scripts/restartsrv_queueprocd) and this did the trick!

    just a followup, eventually I realised that erasing the contents of servers_sched.json wasn't enough because a) null content is not valid JSON b) there has to be a minimum content like ["TaskScheduler","X",{"waiting_queue":[],"nextid":XXX}] without that content, queueprocd starts ok but then fails afterwards

    Hello, I'm glad to see you were able to solve the issue. You can also remove the file completely and then restart queueprocd to regenerate the file if it's corrupted. EX:
    # mv /var/cpanel/taskqueue/servers_sched.json /root/servers_sched.json.backup # /scripts/restartsrv_queueprocd # cat /var/cpanel/taskqueue/servers_sched.json ["TaskScheduler","2",{"waiting_queue":[],"nextid":719}]
    Thank you.
