Subject: Does EPICS Base support multi-thread on vxWorks 6.3?

Hi All,

We developed a client based on libca (EPICS Base 3.14.9), which will create it's own worker thread on construction. But we found it working strangely on vxWorks (ppc-603). Whenever a second EPICS client is created (meaning there are now 2 EPICS worker threads on vxWorks), the CPU usage became 100%.

From the profile, we found the ca_pend_event is consuming lots of the CPU. Meanwhile, it seems epicsMutex is failing to do the lock for the second EPICS client??

Attached is the profile result.



Thanks in advance.

Lorna
