Re: [cobalt-users] logrotate locks up swap space on RAQ3

[Paul Ferwerda <paul@xxxxxxxxxxxx>]

I commented out the analyze_logs stuff out of the split_logs perl script and this morning I didn't get the "swap" leak. I also didn't get the huge spike in swap usage that I had been getting. Since I wasn't using the stat stuff anyway I think that fixed the problem.

[admin@www sbin]$ diff split_logs.orig split_logs
125c125,127
< analyze_logs ($log_type);
