Hi,

i installed a fresh MQ7 on Red Hat 5 Linux x64.

I can start 4 qmgrs without Problems. When i try to start No. 5 i get this error:

"WebSphere MQ was unable to obtain enough storage"

the disk with /var/mqm/qmgrs and /var/mqm/log is 95% empty.

I have two other Red Hat 5 Servers with MQ7 on them (only different Hardware). On this Servers i do not get this error.

Hope someone of you has a hint for me.

Thanks in advanced!

best regards
Sebastian

Location: US: west coast, almost. Otherwise, enroute.

I'll bet there was a msgid amq.... ahead of the "WebSphere MQ was unable to obtain enough storage" message text.

Did you look up the message? Did it refer to disk space or RAM?
