They are recommending a Filter-Max-Stack of 25 since our Filter Levels are not exceeding 14 (based on output of workflow log files), so, I am not sure if this will resolve the Signal 11 problem.
Our ulimit settings are as follows: time(seconds) unlimited file(blocks) unlimited data(kbytes) unlimited stack(kbytes) 4194304 memory(kbytes) 32768 coredump(blocks) 2097151 nofiles(descriptors) 2000 threads(per process) unlimited processes(per user) unlimited Mike. -----Original Message----- From: Action Request System discussion list(ARSList) [mailto:[email protected]] On Behalf Of Grooms, Frederick W Sent: 07 March 2012 15:25 To: [email protected] Subject: Re: Signal 11 error Is it the Maximum Filters for an Operation that is at 10000 or Max Stack of Filters they want changed? Both are at the top of the Advanced tab in the Server Information of the AR System Administration Console. The ar.conf entries are (From the 7.6.04 doc) Filter-Max-Stack Maximum number of recursion levels allowed for an operation. The data modification performed by an AR_FILTER_ACTION_FIELDP filter action might trigger a second set, or level, of filters, one of which might trigger a third level of filters and so on. This option limits the number of times such recursion can happen, preventing the server crash that would occur if the recursion continued indefinitely. The default value is 25. Filter-Max-Total Maximum number of filters that the server executes for a given operation. The default value is 10000.

Is there anything written to the System or Application Event log at the time of that error? Joe -----Original Message----- From: Action Request System discussion list(ARSList) [mailto:[email protected]] On Behalf Of Mike Worts Sent: Wednesday, March 07, 2012 8:29 AM To: [email protected] Subject: Signal 11 error ** Hi all, We just had this error message on our AR Server and I have a few question about it if anyone can help please. 1. Is this a memory error that has caused arserverd to crash as I cannot find any core dumps? 2. Is Signal 11 an application generated error, on an AIX error? 3. What is the relevance of the Form:TMS:Task value 4. We had API/FILTER/SQL logging on at the time, what should I be looking for to point me to the cause?
