ECC6 gateway unreachable : NiIAccept:accept (24: Too many open files)

Hello,

We are regularly facing the same issue on our ECC6 production system

(HPUX Itanium 10.31,Oracle 10.2)

The gateway becomes unreachable (impossible to run the transaction SMGW for example)

And here are the logs of the dev_rd file :

Sun Jan 2 10:42:19 2011

***LOG Q0I=> NiIAccept: accept (24: Too many open files)

      • ERROR => NiIAccept: SiAccept failed for hdl 0 / sock 10

(SI_EMFILE/24; I4; ST; own high 255; max hds 2048)

      • ERROR => GwConnectHandle: GwAccept (socket) failed, rc: -8

GwRebind: rebind service sapgw00 (socket) to port 3300

***LOG Q0I=> NiIAccept: accept (24: Too many open files)

      • ERROR => NiIAccept: SiAccept failed for hdl 0 / sock 10

(SI_EMFILE/24; I4; ST; own high 255; max hds 2048)

      • ERROR => GwConnectHandle: GwAccept (socket) failed, rc: -8

GwRebind: rebind service sapgw00 (socket) to port 3300

It looks like some network issues, but I do not have any tangible proof.

Any idea ?

Thank you very much

Bonne année 2011.

Regards.

Raoul

Here are the paramters

ulimit -a

time(seconds) unlimited

file(blocks) unlimited

data(kbytes) 1048576

stack(kbytes) 8192

memory(kbytes) unlimited

coredump(blocks) 4194303

nofiles(descriptors) 4096

I do not know if these values need to be increased

I just checked sap note 172747 SAP on HP-UX: OS kernel parameter recommendations, but the aforementionned paramters are not indicated.

Regards.

Hi,

Please refer to installation guide for ECC 6 on HP UX and Oracle page 87.

The recommendations here are

time(seconds) unlimited

file(blocks) unlimited

data(kbytes) 2097148

stack(kbytes) 8192

coredump(blocks) unlimited

nofiles(descriptors) 8192

memory(KBytes) unlimited

Important is nofiles , your current settings are half of recommended

Please try adjusting and check if it solves your problem.
