Error description
When the host header for an inbound http request is longer than 256 bytes, stack storage is overlaid. This leads to an 0C4 abend in the controller and this is followed by a hung server. The controller displays the following message when the problem occurs, CEE0374C CONDITION=CEE3204S TOKEN=00030C84 59C3C5C5 00000000 WHILE RUNNING PROGRAM BBOCOMM. AT THE TIME OF INTERRUPT.

A sysmdump that was captured by setting the LE parameter TERMTHDACT(UAIMM) in the controller proc showed that the 0c4 occurred when the following method was executing: HTTP_Request_Parser:: (HTTP_Request_Parser::meta_data_fields*,char*,char*) + 0x638 This apar will address this problem.

Problem summary
**************************************************************** * USERS AFFECTED: Users of WebSphere Application Server for * * z/OS, HTTP services. * **************************************************************** * PROBLEM DESCRIPTION: Controller suffers ABEND0C4/ABENDS0C4 * * while processing an HTTP request with * * a very long host: header value. * **************************************************************** * RECOMMENDATION: * **************************************************************** The WebSphere Application Server for z/OS controller suffers an ABEND0C4/ABENDS0C4 while processing an HTTP request with a very long host: value in the HTTP request header. The host value's long length causes a parse failure, which later causes the ABEND0C4.
Problem conclusion
The parse failure was corrected. APAR PK69371 currently targeted for inclusion in Service Level (Fix Pack) 6.0.2.31 of WebSphere Application Server V6.0.1 for z/OS. Please refer to URL: //www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack availability.
