Version of PMG: Mail Gateway 5.0-61 without subscription key, kernel 4.13.13-5-pve HW: KVM virtual mashine 16Gb Ram, 12 CPU Cores pmg-log-tracker Version: 1.0-1 I have a problem with pmg-log-tracker. I attempt to search entries in Tracking center with filter (any type: Sender/Receiver/Filter) and I get error 500. Then i copy-past the command in bash and get segmantation fault error. My syslog files contains approximetely 660k lines. When I remove all syslog files exept syslog and syslog.1 I get the same error. But if I reduce syslog.1 to 330k lines the error goes away. Dmesg contains following errors after log-tracker gets the error: [60092.789414] traps: pmg-log-tracker general protection ip:561939c8ba63 sp:7ffc4967c010 error:0 in pmg-log-tracker[561939c87000+7000] How I can fix it? Can I fix the problem by sysctl settings? Sorry for my English. Thanks for your help.
