PROBLEM: (QAR 49695) (Patch ID: OSF410-046) ******** Kdebug uses too much memory reading in the kernel symbol table. The full symbol table size can be > 7 MB. Use vmstat -P and look for kdebug line. PROBLEM: (QAR 50184) (Patch ID: OSF410-046) ******** Kdebug sometimes confuses user mode breakpoints and/or single stepping for requests to enter kdebug. If a kdebug prompt appears on the console ("db{0}> ") when either dbx or ladebug is being used for debugging. A hang is also possible due to the following problem. PROBLEM: (QAR 50184) (Patch ID: OSF410-046) ******** Kdebug entry may cause the system to hang. If kdebug is activated on an MP machine, the system may hang with garbled messages printed on the console. PROBLEM: (QAR 51380, 51698, 50184) (Patch ID: OSF410-053) ******** This patch fixes several debugger problems: - Fixes a problem with the ikdebug debugger in which the system panics with the following message: panic: simple_lock: time limit exceeded This problem can occur whenever any exception is encountered while running the debugger. - Fixes a problem in which an AlphaStation 600 as well as other systems may crash when user mode debuggers are in use (for example, dbx or ladebug). This crash occurs because of a misplaced call to the console SAVETERM and only happens if the console variable CONSOLE is set to GRAPHICS.
