Hi Eric, Couple things you might check. Have you checked the indexing against the Run If in the escalations? NULL in the Run If ignores indexing and should be avoided.
If you have a time calculation is the field on one side and the calculation on the other (Create Date < $TIMESTAMP$ - 3600) vs. (Create Date +3600 < $TIMESTAMP$). Calculating on the field value is slower. Is there a SQL query to an external table in the Set Field action? Could be a change/cause there. Likewise is the escalation doing a set field using information from another form that you users frequently use? If so the issue might be the indexing there. These are small things that you can get away with when there is a relatively limited number of records. Then at some magic number the warts start to show. Hope this helps and good luck.

We are experiencing intermittent timeouts with the ARS. Without me doing anything, the AR system becomes normal again after about 5 minutes. All users are getting timeout (or hourglass) but no process is being restarted in armonitor.log. This is the message showing in arerror.log: Tue Jan 18 12:09:24 2011 Dispatch : Timeout during data retrieval due to busy server -- retry the operation (server_name) ARERR - 93 Tue Jan 18 12:10:04 2011 Approve : Timeout during database query -- consider using more specific search criteria to narrow the results, and retry the operation (ARERR 94) In the API log, it shows a 5-minute gap: <API > <TID: 0000000004> <RPC ID: 0000000000> <Queue: Admin > <Client-RPC: 999999 > <USER: Remedy Application Service > /* Tue Jan 18 2011 12:06:16.2224 */-GLEWF OK <API > <TID: 0000000004> <RPC ID: 0000000000> <Queue: Admin > <Client-RPC: 999999 > <USER: Remedy Application Service > /* Tue Jan 18 2011 12:11:16.0001 */+GLEWF ARGetListEntryWithFields -- schema OBJSTR:Class from Unidentified Client (protocol 12) at IP address Our DBA was monitoring the database during the time and found few activities in the database. The activities shown in SQL log during the timeout were all for user AR_ESCALATOR, which means the escalation was still running during the time. This can also be verified from the escalation log. When this occurs, the CPU and RAM utilizations are dramatically dropping to the lowest levels on both the ARS server and the database server. There was no application change in the last couple of months. The problem started about two weeks ago. It could occur 3 times a day and sometimes it works fine for days without it occurring. Our configuration/environment: ARS: 7.1 patch 7 ITSM: 7.0.03 patch 9 SLM: 7.1 patch 2 SRM: 2.2 patch 4 Midtier: 7.6.03 ARS Server: Solaris 10 (16 GB of Physical Memory, 18 GB of SWAP, 8 CPUs) - Dedicated to ARServer, ITSM, SLM, and SRM. Midtier Server: Windows Server 2003 SP2 (2 CPUs, 2 GB of RAM) - Used only by customers to submit service request. Database: Oracle: 10gR2 (remote) The following are threads settings in ar.conf: Private-RPC-Socket: 390601 2 6 Private-RPC-Socket: 390603 2 2 Private-RPC-Socket: 390620 16 24 (FAST) Private-RPC-Socket: 390626 8 16 Private-RPC-Socket: 390627 2 12 Private-RPC-Socket: 390635 24 30 (LIST) Private-RPC-Socket: 390680 24 24 Private-RPC-Socket: 390693 2 4 Private-RPC-Socket: 390698 2 4 We have about 300 concurrent Remedy users during the peak hours. ARServer is running as non-root process. The number of open file descriptors for arserverd (~700) was well below the ulimit 3072. The FAST and LIST threads never reached the maximums. I have an open ticket with BMC Support but thought I might get a solution quicker from the Arslist here.
