Description:  [reply]  	 Opened: 2006-03-08 02:08

squid 2.5 stable12 is constantly growing in memory size.
cachemgr reports that cbdata connstate is the offender:

cbdata ConnStateData (4)        184     6070727 1090834 1090834 0.00    88     
6070727 1090834 1090834 100

squid is using 1.090.834 KB for connstate data, wich is 88% of its total
memory.
bow has 2GB of ram but is swapping. furthermore, this number is constantly
growing.
and squid has only been up for 2 days:
Start Time:     Mon, 06 Mar 2006 10:14:43 GMT
Current Time:   Wed, 08 Mar 2006 09:04:38 GMT

Nice part is that we have 2 exactly identical boxen and that this problem hits
only one of them. clients are distributed amongs them by round-robin dns I am
sure that one client use is causing this but finding it is rather difficult.

what could I send more to help on this ?
