Fatal errors during several statements
Hi everyone,
At a customer we face recurring IQ fatal errors.
To see if upgrading IQ helps, we tried SP04 patch 6, SP04 patch 9, SP10 patch 01, and currently, on the test environment, we have SP10 patch 10.
In all these versions, the same error occurs every now and then. Unfortunately not reproducible, which makes it hard to file an SAP incident.
All stack traces are similar to this one:
** Error from IQ connection:
** Time of error: 2016-08-25 10:07:07
** IQ Version: SAP IQ/16.0.101/20034/P/sp10.01
** OS info: IQ built on: MS/Windows 2003, Executed on: Windows/IQP01/WinNT/6.1/Build 7601/Service Pack 1/x86 Family/level 6/Model 23/Stepping 6/32 CPU(s)
** Command status when error occured: CURSOR ACTIVE
** Command text:

<etc etc etc>
See attached XLS file for an overview of all crashes in the past years. The actual load tables are masked, but they are different every time. So it's not like the crashes occur on only one table.
All environments run Windows Server 2008 R2 Enterprise, with multiple CPU/mem configurations.
Test: 8 cores, 64 GB RAM
Acc: 8 cores, 64 GB RAM
Prod: 32 cores, 192 GB RAM
DB files are on a SAN, using mounted NFS partitions. Using files, not raw devices.
Any ideas?
