I couldn't find anything though that described a > "fix". Is there a fix? Or is the fix to get a faster server? :-) For the issue where you get the wrong error message, that was fixed in 1.6 as Jeff described. For the issue where the server takes "too long", there is no single fix, because the cause is different in a variety of situations. In some cases, there is no fix, because sometimes disk operations just take that long. Jeff mentioned a general possible cause involving callbacks, but other things can cause it, too. If it is disk-performance-related, sometimes using '-sync never' can help. The only sure-fire way to know what the cause is is to raise the debugging level when it happens, or capture a core or pstack, etc. Anything that causes the operation to take longer than a minute on the server side causes that to happen. For the issue of the ridiculous behavior that a server kills a call after it runs for a minute, that is not yet fixed. There is a series of changes starting with http://gerrit.openafs.org/10773 that are a proposed fix for that, but it's not a priority for me at the moment, so it's not getting attention. There is some care to be taken there with changing timeout-related behavior to make sure nothing else is broken at the same time. > The discussion that I am referring to took place in October of last year > with the subject "No buffer space available" reported by Stephan > Wiesand. > > This is the last of the discussion that I have found: For reference, this is referring to this thread, I believe: <http://lists.openafs.org/pipermail/openafs-info/2013-October/040178.html> -- Andrew Deason adea...@sinenomine.net _______________________________________________ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
