Re: UCX Memory Problem
Was there any messages in operator.log?

Re: UCX Memory Problem
$ UCX SHOW COMM and $ UCX SHOW COMM/MEM will show the amount of data structures allocated and used by UCX.
Please check, whether the peak values of any resource have reached their maximum value.

Re: UCX Memory Problem
Yes Volker, Large Buffers is reaching it's peak value of 200 and after that wait started increasing and finnaly wait reach to such a value that UCX stops working.

Re: UCX Memory Problem
once the Large Buffers have all been used up and you start seeing Large Buffer Waits increasing, you would need to shut down and restart UCX or even reboot your OpenVMS VAX system for recovering the resources used by UCX.
What are the Large Buffers being used for ? UCX SHOW COMM and UCX SHOW COMM/MEM should show the usage for the Large Buffers. Does the usage increase over time (possible memory leak) ? Maybe you need to tune your UCX subsystem and provide more Large Buffers ?
Volker.

Re: UCX Memory Problem
We did server reboot to resolve the problem but it again appears in the following night at same time. so, finally we have found the cause for the problem which was external to my server. Thanks.

Re: UCX Memory Problem
thanks for the update. If you could describe the problem causing the Large Buffers to be consumed (maybe in some generic terms, if you don't want to get too specific), this may help others under similar circumstances.
Thanks,
Volker.
