How do you interpret `strace` on an apache process returning `restart_syscall`?
- by indiehacker
We restart an apache server every day because RAM usage reaches its limit.
Though of value See this serverfault answer, I dont think lowering the MaxClients in the apache configuration is a solution to the unknown root problem.
Can you make sense out of the below data?
Below is an extract of what
$top with M
returns:
20839 www-data 20 0 1008m 359m 22m S 4 4.8 1:52.61 apache2
20844 www-data 20 0 1008m 358m 22m S 1 4.8 1:51.85 apache2
20842 www-data 20 0 1008m 356m 22m S 1 4.8 1:54.60 apache2
20845 www-data 20 0 944m 353m 22m S 0 4.7 1:51.80 apache2
and then investigating a single process with
$sudo strace -p 20839
returns only this one line, which is cryptic, for me:
restart_syscall(<... resuming interrupted call ...> <unfinished ...>
Any insights? Thanks.
