The socket is setup as AF_UNIX, SOCK_STREAM. It works most of the time, but occasionally gets this error. The receiving end of the socket appears to be working properly. I know this isn't very detailed, but I'm just looking for general ideas. Thanks! c linux sockets unix share|improve this question edited Jan 17 '13 at 9:40 Ashwini Chaudhary 131k20196274 asked Jan 17 '13 at 0:49 giroy 73841634 Is this related? stackoverflow.com/questions/5737493/… –paddy Jan resource temporarily unavailable python 17 '13 at 0:52 2 Are you setting your socket to O_NONBLOCK ? –Deepankar Bajpeyi Jan 17 '13 at 0:57 I don't think it is related to that post. My sockets are SOCK_STREAM which I believe are blocking which is what I want. –giroy Jan 17 '13 at 0:59 2 Whether a stream is blocking or non-blocking is independent of whether it's SOCK_STREAM or SOCK_DGRAM. The answer there is relevant. –Barmar Jan 17 '13 at 1:33 add a comment| 2 Answers 2 active oldest votes up vote 35 down vote accepted "Resource temporarily unavailable" is the error message corresponding to EAGAIN, which means that the operation would have blocked but nonblocking operation was requested. For send(), that could be due to any of: explicitly marking the file descriptor as nonblocking with fcntl(); or passing the MSG_DONTWAIT flag to send(); or setting a send timeout with the SO_SNDTIMEO socket option. share|improve this answer answered Jan 17 '13 at 1:21 caf 155k14192324 The cause of my problem was setting the send timeout.

But the control files is exists. Means OS is not able to use the control file as its is in lock resource temporarily position. So what should we do in that case. Approach : 1. shutdown the instance 2. Go the location where control file exists 3. Move the controlfile to new name and then revert to existing name 4. Start the database Note : This solution is also work for all database.

Resource temporarily unavailable (Thread Problem on Linux) Reported by: whocares Owned by: phk Priority: normal Milestone: Component: varnishd Version: trunk Severity: normal Keywords: Cc: Description Today I tried kristian's Performance tips on a Linux box and ran into the same problem as was already mentioned in #85: Depending on what box I tried, I never managed to get more than 238 to 302 threads. The reason for that behaviour is that on Linux the number of threads that can be started is essentially limited by the stack size occupied by every thread. In a standard configuration every thread will get 8 MByte of stack attached to it. Thus, in conjunction with other memory related limits in a standard Linux environment you'll never ever get more than around 240 to 300 threads. You can however modify the thread's stack size before creating the thread by doing something like this: include "bits/local_lim.h" pthread_attr_t attr; pthread_t thread[1024*1024]; size_t size; /* do some calculation for optimal stack size or ... */ size = PTHREAD_STACK_MIN; pthread_attr_init(&attr); pthread_attr_setstacksize(&attr, size); pthread_create(&thread[somecounter], &attr, (void *)&function_to_run, NULL); ... On Linux this will set the stack size to 16384 bytes which of course is way too small, but allows for around 32.000 threads to be created on my test box. If you like to rum some tests for yourself I attach a sample C program to test different thread stack sizes on a Linux box. It's possible that the code will run on other platforms, too, but I didn't test that. Anyway, it would be nice if varnish would set it's thread's stack size to a reasonable value so that poor Linux users can enjoy at least some of the performance that is possible on FreeBSD and Solaris ;) Attachments thread-limit.c (1.5 KB) - added by whocares 2009-11-01T15:27:09+01:00 ago.
