You're out of virtual memory -- you haven't configured enough swap
space. And your server wants some more memory and can't get it.
Speaking personally, and only with respect to non-production systems, I
always place an upper limit on the amount of shared memory that any
OnLine system is allowed to use via the SHMTOTAL parameter in the
onconfig file. I would probably try that on production systems too, but
others may disagree with me and have the experience with production
systems to provide counter-arguments for why it is a bad idea to control
the amount of memory OnLine is allowed to use.
Also, it would be sensible when you next ask a question to include some
extra information, such as which version of Informix you are using, and
which platform you are running it on.

Thank you all!!
There was a leak in our cursor LIB! :-(
Anyhow I still get some -208 error on some join selects using inf. dbaccess.
The Server is an Aix 4.2 with Online 7.2 on .
By the way paging space is all right and no limits on SHM in config.!!
