Package: logrotate
Version: 3.7.1-3
Severity: critical
Justification: breaks unrelated software
I woke up this morning to find my webserver (lighttpd) unresponsive and
logrotate
using up 100% CPU. When I ran strace on logrotate I found:
rename("/service/lighttpd/logs/error.log.638155266.gz",
"/service/lighttpd/logs/error.log.638155267.gz") = -1 ENOENT (No such file or
directory)
rename("/service/lighttpd/logs/error.log.638155265.gz",
"/service/lighttpd/logs/error.log.638155266.gz") = -1 ENOENT (No such file or
directory)
rename("/service/lighttpd/logs/error.log.638155264.gz",
"/service/lighttpd/logs/error.log.638155265.gz") = -1 ENOENT (No such file or
directory)
rename("/service/lighttpd/logs/error.log.638155263.gz",
"/service/lighttpd/logs/error.log.638155264.gz") = -1 ENOENT (No such file or
directory)
rename("/service/lighttpd/logs/error.log.638155262.gz",
"/service/lighttpd/logs/error.log.638155263.gz") = -1 ENOENT (No such file or
directory)
rename("/service/lighttpd/logs/error.log.638155261.gz",
"/service/lighttpd/logs/error.log.638155262.gz") = -1 ENOENT (No such file or
directory)
rename("/service/lighttpd/logs/error.log.638155260.gz",
"/service/lighttpd/logs/error.log.638155261.gz") = -1 ENOENT (No such file or
directory)
rename("/service/lighttpd/logs/error.log.638155259.gz",
"/service/lighttpd/logs/error.log.638155260.gz") = -1 ENOENT (No such file or
directory)
rename("/service/lighttpd/logs/error.log.638155258.gz",
"/service/lighttpd/logs/error.log.638155259.gz") = -1 ENOENT (No such file or
directory)
Apparently it had missed a lighttpd log file or something and was now
proceeding
to logrotate every imaginary file it could think of. (It's hard to be sure of
exactly what's going on without looking at the code.)
I killed it and the site came back, but I thought a developer would know better
what's going on.
I haven't changed the logrotate conf files in months and this has never
happened
before. The relevant config is:
/service/lighttpd/logs/*.log {
weekly
missingok
copytruncate
rotate 999999999
compress
notifempty
sharedscripts
postrotate
if [ -f /var/run/lighttpd.pid ]; then \
if [ -x /usr/sbin/invoke-rc.d ]; then \
invoke-rc.d lighttpd force-reload > /dev/null; \
else \
/etc/init.d/lighttpd force-reload > /dev/null; \
fi; \
fi;
endscript
}
