guimfacq, You could try increasing the memory and message limits set for STREAMS using the -c and -C flags to the 'streams' utility function. They are likely set to default values that might inappropriately low for such a high performance, large memory system.
Nevertheless, the assertion failure might be related to something else, (most likely an SMP race condition aggravated by waiting for a buffer). I think that you will need to contact Intel to resolve the problem. --brian On Thu, 27 Apr 2006, guimfacq ghislain wrote: > > Hello, > > Can anyone please advise on the following problem i am encountering: > > I am using LiS-2.15, with Dual Xeon 3.06/hyperthreading active machine > and 2GB of RAM > > after a while of operation, var/log/messages is reporting assert in a > stream driver (mercd) > > Apr 21 18:15:09 fe2 kernel: MercRcvDataFromAdap: RecvData() failed. > > Apr 21 18:15:10 fe2 kernel: Buffer is unavailable waiting > > Apr 21 18:15:10 fe2 kernel: mercd: assert(NULL) failed in file > > build/bld_obj/msddpc.c, line 186 > > Apr 21 18:15:10 fe2 kernel: StreamOpen: Adapter State not ready. > > Apr 21 18:15:25 fe2 last message repeated 53 times > > Meanwhile the linux streams -s command shows 2 failures in the memory > allocating calls > > ----------------------------------------- > > vie abr 21 > 18:16:03 CEST 2006 > > ----------------------------------------- > > Current Total Maximum Failures > > STREAMS Files Open : 186 636 186 0 > > Memory Allocator Calls : 11488210 11488210 11488210 > 2 > > Memory Free Calls : 11444091 11444091 11444091 0 > > Bytes Allocated : 18874608 2389024160 18875520 > 2 > > The LiS failure is likely suggesting that messages were not getting > sent to driver/ driver failing to allocate messages. > > i am however not sure what needs to de done to overcome that: > > Add more RAM?
