I've got 100 Netware 5.1 servers with:
TSM client 4.21
Netware sp2a
tsa5up7 patch
filesys & ncp patch

my dsm.opt file contains the option >
managedservices SCHEDULE WEBCLIENT

When I open the weblclient to backup/restore or even look at help, it often
abends.
It appears to be trying to free memory.   It is not reproducible on demand.

Is anyone else seeing this problem?

The following information is from the abend.log.

    ESI = 00000000 EDI = C0621DC4 EBP = C0C50E00 ESP = C0C50DF4
    EIP = C0536193 FLAGS = 00210246
