Steps to reproduce:
- Upgrade 6.4 to 7.0 with one scheduled report
Result:
CPU utilization for report manager is almost 100%, always:
Expected:
No load because there is one daily report
Analysis:
strace repeats these lines in an endless loop:
newfstatat(AT_FDCWD, "/etc/localtime", {st_mode=S_IFREG|0644, st_size=2298, ...}, 0) = 0 openat(AT_FDCWD, "/etc/localtime", O_RDONLY|O_CLOEXEC) = 20 newfstatat(20, "", {st_mode=S_IFREG|0644, st_size=2298, ...}, AT_EMPTY_PATH) = 0 newfstatat(20, "", {st_mode=S_IFREG|0644, st_size=2298, ...}, AT_EMPTY_PATH) = 0 read(20, "TZif2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\t\0\0\0\t\0\0\0\0"..., 4096) = 2298 lseek(20, -1449, SEEK_CUR) = 849 read(20, "TZif2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\t\0\0\0\t\0\0\0\0"..., 4096) = 1449 close(20)
The last line from the report manager on the server start:
11601:20241025:204647.838 In rm_report_calc_nextcheck() now:2024.10.25 20:46:47
This function never returns. Not sure, but this might mean there is something wrong in the loop in zbx_get_report_nextcheck()
