I found that WWSTATE was not being cleaned up well. I wrote my own program to clean things up every night (GARBAGE.COLLECT2). It run from cron every night and cleans up everything: WWSTATE, SAVEDLISTS, and other files unique to our application. It also archives things as needed. It keeps things running fairly tightly.

My understanding (and others please correct me if I am wrong) is that the WWSTATE table is one of 3 things the Redback garbage collection cleans out (WWSESSION and some SavedLists are the other two). You can manually run a garbage collection from the RB.ADMIN menu I mentioned before. You can also inspect the logs from previous garbage collections using a different option on the menu. If the Redback garbage collection isn't running, then that is most likely the cause for your slowness. Planning some downtime and re-sizing the WWSTATE table and looking at your garbage collection parameters is probably something to consider, even after you get garbage collection running again.

Ryan thanks for that. Our WWSTATE file is indeed poorly sized Is this something we are supposed to be periodically clearing out ? Or is some garbage collection process broken that supposed to be clearing these old entries? -----Original Message----- From: Ladd, Ryan <[email protected]> To: u2-users <[email protected]> Sent: Wed, Jan 22, 2014 9:35 am Subject: Re: [U2] Time for a Redback upgrade ? Here are some suggestions. -use showrgw and perfrgw to inspect your responders and their response time. -check your Redback Garbage Collection (>RB.ADMIN, option 2) settings and logs. Additionally, check the WWSTATE table to ensure it is sized appropriately. If that table is poorly sized, your response time will suffer. -turn on more verbose logging and inspect the output of rgw.log (this requires a "bounce" of redback, so this may or may not be possible depending on your uptime requirements). There are more things to look at, but these should at least give you a chance at looking in the right direction.

We are Running Redback 4.4.0.1526 Build 1527 which is stamped 29 May 2007 This is running on Windows Server 2008 R2 Standard We've lately been experiencing odd slowness.
