Environment

Issue



After migrating Symantec Endpoint Protection (SEP) clients to 12.1.1 (RU1), Lotus Notes crashes with a NLNHOOK.EXE error.


Error



PANIC: semaphore invalid or not allocated

Additional errors

Faulting application name: nlnhook.exe, version: 12.1.1000.157, time stamp: 0x4eadfee9
Faulting module name: nlnvp.dll_unloaded, version: 0.0.0.0, time stamp: 0x4eadfffb
Exception code: 0xc0000005
Fault offset: 0x5d458ad3
Faulting process id: 0xc34
Faulting application start time: 0x01cd4ba2c3db7f29
Faulting application path: C:\Program Files\Symantec\Symantec Endpoint Protection\12.1.1000.157.105\Bin\nlnhook.exe
Faulting module path: nlnvp.dll
Report Id: 02e13191-b796-11e1-aa2f-180373af6ff2


Cause



The notes.ini file does not contain anything related to NLNVP, or it contains only an old reference to this add on.


Solution



This issue is resolved in SEP 12.1.2 (RU2).  Please download the latest version of Symantec Endpoint Protection.

 

Symantec Endpoint Protection and Lotus Notes both crash with Lotus Notes plug-in installed (enabled or disabled)
Fix ID: 2665371
Symptom: The Lotus Notes Email Auto-Protect plug-in crashes, which cause Symantec Endpoint Protection and Lotus Notes to crash. These crashes occur even if you disable the plug-in.
Solution: Added code to better clean up after previous installs, and to update the notes.ini file before nlnvp.dll is launched.
 

 

If an upgrade is not immediately possible, the following workaround will also succeed:

Open notes.ini with a text editor and add the line ExtMgr_Addins=NLNVP after the line  NAMES=names.nsf

Also delete line NSF_HOOKS= NLNVP.DLL if present.

Or if ExtMgr_Addins= is empty, make sure it is complete as stated above.
