Hi,

One of my costumer has a problem with an Estrella AIX 4.2.
It regularly becomes frozen : about once a month.

Last time it happened, the operator reboot it.
A system dump was then proposed.

Here are some informations about this system dump.

Should it show the reason why the calculator became frozen ?
Does it mean there is a file system problem (jfs_rdwr in trace), an
Oracle (7.3.4) problem or anything else ?
What does the "207" abend code mean ?
What could I do to resolve the problem ? diag, fsck, Oracle
installation ?

Thanks
Nicolas.

207 is usually hardware related ... run diags in PD mode...
