Look at it's log file and console spool file to see what it was doing when the error occurred. The message is typical for an exec that executes something that executes the exec, as Stephen pointed out.

If you've configured VMSERVE properly it is fairly unusual for it to suddenly change it's behavior unless a disk it is linked to has introduced something new.

Of course this also assumes that all the EXECs that you've given it to use follow the Good Rexx Coding Practices rules.

Hi,

We are running VMSERVE, the application server/scheduler on a z/VM CP/CMS
system. Recently, it started giving this error every time we make a progr am run through VMSERVE. I am not very experienced in z/VM so any help is appreciated!

System : z/VM Version 5 Release 2.0, Service Level 0801 (64-bit)
WWVM ESA CMS 15 012

VMSERVE starts fine but as soon as it runs a program, VMSERVE crashes and
ends with this error,

DMSITS135S Maximum SVC depth 200 has been exceeded.
DMSITS135S Maximum SVC depth 200 has been exceeded.

It probably means : The CMS system does not allow the nesting level of SV
Cs to exceed 'nnnn'. But not sure what can be done to fix this.

Regards,
Amar
