Is this Linux or some other OS?

 

It looks like you will need to kill the IOC process.

No effect from ^C whatsoever. Typed epicsMutexShowAll 1

3 times to blank screen – no response

Can you type ^C to abort the casr command?  It could be a deadlock.  If that works then type

 

epicsMutexShowAll 1

 

several times and see if the same mutexes are always locked.   That is the symptom of a deadlock.

Hi,

We have suddenly situation we can no longer connect to ca channels, (while the existing connections are served)

casr 4

181888 bytes allocated

       Send Lock:

           epicsMutexId 0x7f3978036420 source ../../../src/ioc/rsrv/caservertask.c line 1231

       Put Notify Lock:

           epicsMutexId 0x7f3978036450 source ../../../src/ioc/rsrv/caservertask.c line 1232

       Address Queue Lock:

           epicsMutexId 0x7f3978036480 source ../../../src/ioc/rsrv/caservertask.c line 1233

       Event Queue Lock:

           epicsMutexId 0x7f39780364b0 source ../../../src/ioc/rsrv/caservertask.c line 1234

       Block Semaphore:

           epicsEvent 0x7f3978010c90: full

    pthread_mutex = 0x7f3978010c90, pthread_cond = 0x7f3978010cb8

    TCP client at 10.0.153.12:54302 'box64-3':

       User 'rose', V4.13, Priority = 0, 75 Channels

       Task Id = 0x7f397803c750, Socket FD = 44

       2262.05 secs since last send, 2262.04 secs since last receive

       Unprocessed request bytes = 424, Undelivered response bytes = 0

       State = up

 

Then the output stopped …. no response any more on the console

 

EPICS_BASE=base-3.15.8

 

Any ideas?
