![]() APAR status Closed as program error. Error description The application servant regions generates an EC3 abend, with reason code 04060012. The associated control region will have no more available storage. The EC3 dump will show the system in cross memory mode from the servant region (SR) to the control region(CR).A review of recent CR GETMAINs will show a pattern of ever increasing requests (increasing by 2000). Here is a sample: DQE: Addr 58502000 Size 402000 FQE: Addr 58903668 Size 998 DQE: Addr 58904000 Size 404000 FQE: Addr 58D075A8 Size A58 DQE: Addr 58D08000 Size 406000 DQE: Addr 58D08000 Size 406000 FQE: Addr 5910D4E8 Size B18 DQE: Addr 5949A000 Size 408000 FQE: Addr 598A1428 Size BD8 ...... The application server will also have SMF record creation enabled, probably with a substantial server_SMF_interval_length.Local fix Disable SMF. A great reduction in server_SMF_interval_length may greatly reduce the likelihood of a storage related error.Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V5.0 for z/OS * **************************************************************** * PROBLEM DESCRIPTION: ABENDEC3/ABENDSEC3 reason code 04060012 * * encountered by servant. * **************************************************************** * RECOMMENDATION: * **************************************************************** Servant running in cross memory mode, attempted to get controller private storage but the request failed. The request failed because most of the controller private has been obtained as LE heap storage. The controller SMF code obtains its buffers from LE heap storage. The buffer size starts out at 8000 bytes and grows by 8000 bytes until a buffer that is large enough is obtained. The buffers along the way are returned to LE and are available for use by other users of the LE heap. The servant was trying to obtain controller private from the system not from the LE heap.Problem conclusion Changed the code to double the size of the SMF buffers while the buffer is less than 4096000. When the buffer is greater than 4096000 the buffer will grow by about 20 percent. APAR PK13550 is associated with SERVICE LEVEL W502036 of WebSphere Application Server V5.0 for z/OS.Temporary fix Comments
