Guardian Procedure Errors and Messages Manual

Effect For trap 4, process control passes to the Debug or Inspect debugger or to the trap handler
designated by a call to the ARMTRAP procedure, or else the process is abended. For further
information, see “Trap Handling” (page 273).
For the signal SIGTIMEOUT, the default or specified signal handling occurs. For further information,
see “Signal Handling” (page 274).
Note that the loop-timer trap or signal is disabled after the trap or signal is generated; the loop-timer
trap or signal will not recur unless it is rearmed by another call to SETLOOPTIMER.
Recovery Recovery is application dependent. It is possible to resume from both trap 4 and
SIGTIMEOUT, continuing the program from the site of the interruption.
SIGLIMIT, Trap 5 Limits exceeded
Cause This condition occurs for one of the following reasons:
• The process called an operating-system procedure that tried to place a process identification
number (PIN) greater than 255 into a 1-byte field.
• A TNS Guardian process invoked a procedure or function that is allowed only for an OSS or
TNS/R native process.
Effect For trap 5, process control passes to the Debug or Inspect debugger or to the trap handler
designated by a call to the ARMTRAP procedure, or else the process is abended. For further
information, see “Trap Handling” (page 273).
For the signal SIGLIMIT, the default or specified signal handling occurs. For more information, see
“Signal Handling” (page 274).
Recovery Run the process at a low PIN or recode the process.
Trap 8 (Signal delivered to TNS process)
Cause A trap 8 is generated when, under very rare circumstances, a signal is delivered to a TNS
process.
Effect Process control passes to the Debug or Inspect debugger or to the trap handler designated
by a call to the ARMTRAP procedure, or else the process is abended. For more information, see
“Trap Handling” (page 273).
Recovery Contact your system manager.
SIGMEMMGR, Trap 11 Memory manager read error
Cause A hard (unrecoverable) read error occurred while the program was trying to bring a page
in from virtual memory.
Effect For trap 11, process control passes to the Debug or Inspect debugger or to the trap handler
designated by a call to the ARMTRAP procedure, or else the process is abended. For more
information, see “Trap Handling” (page 273).
For the signal SIGMEMMGR, the default or specified signal handling occurs. For more information,
see “Signal Handling” (page 274).
If the trap or signal occurred because the disk containing the swap file went down, the process
abends, regardless of the selected trap or signal handling.
Recovery Recovery is application dependent. Usually, this condition occurs when both the primary
and backup paths to a disk are down. Contact your system manager to resolve the problem.
