Re: Lock expired?

[Aleksandar Ivanisevic]

Ok, so how do I tell what holds the second lock and why?

# cfshow --active 
lock..xxx.cfexecd.cfexecd_1243 = Wed Jun 29 16:04:38 2005

lock.cfagent_conf.xxx.link.link_4052 = Tue Oct  4 13:07:30 2005

lock.db.localhost.cfenvd.cfenvd_1258 = Wed Jun 29 16:04:31 2005

# ps -ef | grep cf
root      1767     1  0 Jun29 ?        00:00:03 cfservd
root      1787     1  0 Jun29 ?        00:08:22 cfenvd
root      1796     1  0 Jun29 ?        00:00:55 cfexecd
root     28428 28296  0 14:24 pts/0    00:00:00 grep cf

In the cfengine.log around that time I see normal hourly run of cfagent
and bunch of locks removed, but not that one.

In the log I also see:

# grep -v "normally" /var/cfengine/cfengine.runlog
