ITS Agate needs restarting

[Former Member]

I am using ITS 620 patch 16 on Windows 2003. I have 1 Wgate and 2 separate Agates on two separate servers.

I have a problem and I am unsure what is causing the problem.

From time to time, approximately every 3 days when I try and access the ITS I get HTTP 500 page can not be displayed. If I stop and restart the Agate service users are able to log back onto ITS.

I am looking through the logs however am unable to find anything conclusive. How can I increase the logging to help me debug this issue.

Currently I am just using what ever the default logging is set to

Any help would be good.

Hello Ajay,

Like you said, it looks like you're running out of workthreads. You should probably increase the MaxWorkthread and MinWorkthread values (these should always be equal). But you should also see if the workthreads ever get released...meaning, in the performance.log (or loadstat.log) if the number of available workthreads ever increases after a decrease. If it only decreases then you either have a workthread hanging problem or your users are very active. In either case your ITS installation should be upgraded or looked at by SAP (open a message under component BC-FES-ITS).

Hi I checked within the performance log and I had the following:-

2006-01-11T09:16:18.907 😧 0 365 400 9 40 0.000

2006-01-11T09:17:18.907 😧 0 364 400 7 40 0.000

2006-01-11T09:18:18.907 😧 0 360 400 3 40 0.000

2006-01-11T09:19:18.907 😧 0 360 400 2 40 0.000

2006-01-11T09:20:18.907 😧 0 360 400 2 40 0.000

2006-01-11T09:21:18.907 😧 0 359 400 0 40 0.000

which suggests that I have run out of workthreads. The default is 40. My agate servers have 4Gb ram and 1 cpu 3.19 GHz. Currently the CPU utilisation is 0 and 2.2Gb of ram is free.

I think that I have to bump up the minworkthreads and maxworkthreads.

Is this what you did ?

Hi Ajay,

it looks like you have hanging workthreads. I would recommend you to upgrade to the latest ITS Patch (currently 20) since we fixed problems with hanging workthreads recently.

I would not recommend you to increase the number of workthreads since then you would hit to process limit of 2GB addressspace. I would rather recommend you to use a second agate process and decrease the number of min/max workthreads to 30 and the numer of sessions to 300 which makes then 60 workthreads and 600 sessions.

Anyway I don't think you have a load problem at all so you can leave the system as is if you do the upgrade.

I think you must check properties of disconnecting users.

AGate has a limit of threads, so if max number of threads is reached then it stops.

I put some additional parametrs and everything became good.
