531E

<num> Buffer size exceeded ‑ compiler terminating

Reason

The rule buffer or message buffer overflowed at line <num>. This message can occur for a variety of reasons including

The number of error messages issued caused a storage overflow. The compiler is terminating.
CA ACF2 for z/VM found more than 250 rule entries in the rule. The maximum number of rule entries (parameter MAXRULE on OS/390 systems) is limited to 250 rule entries in VM.
The total size of compiled rules is limited to 4088 bytes of compiled rule data. The number of bytes of the compiled rule might have exceeded this threshold.

The variable <num> is the line number of the rule entry that is causing the buffer to overflow.

Action

If CA ACF2 for z/VM displayed errors, correct them and try again. If there are more than 250 rule entries, reduce them by using masking or NEXTKEY. If the rule set is too large, simplify the rule set and try again.

When you compile a rule, the compiler reports the number of bytes and the percent of available space. It can be helpful to make a copy of the rule and reduce the size to one less than the line number reported by <num>. Recompile the rule with the NOSTORE option to get an idea of how big the compiled rule is. If you need additional assistance, contact CA Support.
