Problem summary
**************************************************************** * USERS AFFECTED: IMSTM users that use EGL are affected by * * this APAR. * **************************************************************** * PROBLEM DESCRIPTION: There is a memory leak in the IMS * * environment with EGL. The * * functionality is fine, but each * * transaction can cause a leak * * of the heap memory blocks. * * This was because the runtime call * * to release this memory was * * skipped due to a mismatch in * * the parameter passed. The EGL * * generated cobol program was * * skipped due to a mismatch in * * the parameter passed. The EGL * * generated cobol program was * * passing "EGLFREE" but the * * runtime was looking for * * "EGLFREE " (notice the space). * * Because the cobol program's * * value did not have a trailing space, * * this caused the runtime function * * to not happen, as the parameter * * was not determinable. This * * in turn caused the memory to * * remain allocated, but unused. * **************************************************************** * RECOMMENDATION: Apply this maintenance * **************************************************************** There is a memory leak in the IMS environment with EGL. The functionality is fine, but each transaction can cause a leak of the heap memory blocks. This was because the runtime call to release this memory was skipped due to a mismatch in the parameter passed. The EGL generated cobol program was passing "EGLFREE" but the runtime was looking for "EGLFREE " (notice the space). Because the cobol program's value did not have a trailing space, this caused the runtime function to not happen, as the parameter was not determinable. This in turn caused the memory to remain allocated, but unused.
Problem conclusion
The runtime has been updated to check for "EGLFREE" without the need for any trailing space. No programs need to be regenerated as this is entirely a runtime fix.
