The SAS/SHARE server cannot support concurrent HOST sorts.  System
abends may occur in the form of an 0C1 or an 0C4 when concurrent
HOST sorts are invoked under a single address space within a SHARE
server session.

It is possible to see similar messages like these in the SHARE SAS Log:

   ERROR: Sort did not complete successfully. See messages on the
          Job Console Log or //SYSOUT data set.
   ERROR: System abend 0C4 occurred in module UNKNOWN at location xxxx.
   ERROR: System abend 0C1 occurred in module UNKNOWN at location xxxx.

Invoking sorts on the SERVER side either with PROC SORT or PROC SQL with
an ORDER BY, DISTINCT, or GROUP BY clause is discouraged.  Staggering
index jobs or other jobs that cause concurrent sorting on the server
would be a good operational practice.
