Max Size in Msg Snd

Hi

We are encountering this error message on
msgsnd () whenever we try to send across a larger message greater than around char[1200].

msgsnd: Resource temporarily unavailable

Are there any kernel params that control the behaviour of msgsnd.

Wld appreciate any advice..

Thanks..

Re: Max Size in Msg Snd

Hi,

See the following kernel parms:

msgmax => Max size in bytes of a msg in a queue
msgmnb => Max size of a single msg queue
msgmni => Max # of msg queues
msgtql => Max # of msgs in the system (all queues)

HTH,
Jeff
