Error description

  • When the IBM Process Portal search index is being built, the
logs might report hung threads in messages like the following
message:

[12/30/17 4:06:32:685 SAST] 0000008e ThreadMonitor W
WSVR0605W: Thread

Local fix

  • Prevent multithreading from being used when the index is being
built by setting the following configuration property in the
100Custom.xml file:

<search-index merge="mergeChildren">
<process-index-batch-size>1000</process-index-batch-size>
</search-index>

Problem summary

  • No additional information is available.

Problem conclusion

  • A fix will be available for a future release of IBM BPM that
prevents hung threads from occuring when the Process Portal
search index is being rebuilt.

Temporary fix

  • Not applicable.
