Description

On all Junos platforms with ephemeral configuration, multiple daemons like chassisd, dcd, l2ald, l2cpd, mib2d and transportd crash upon ephemeral or static db commits causing service traffic impact. 
The services will self recover after the issue is hit in the network.


Symptoms

The crash appears to be due to a segmentation fault (SIGSEGV) across different daemons during operations involving ephemeral commits or static db commits with some ephemeral configuration present.
 The below command can be used to check the crash files:

user@device>show system core-dumps | no-more
rw-r----- 1 <date> <time> var/tmp/chassisd.core-tarball.0.tgz
-rw-r----- 1 <date> <time> var/tmp/dcd.core-tarball.0.tgz
-rw-r----- 1 <date> <time> var/tmp/l2ald.core-tarball.0.tgz
-rw-r----- 1 <date> <time> var/tmp/l2cpd.core-tarball.0.tgz
-rw-r----- 1 <date> <time> var/tmp/mib2d.core-tarball.0.tgz
-rw-r----- 1 <date> <time> var/tmp/transportd.core-tarball.0.tgz


This issue might be seen if the following conditions are met:
* On all Junos platforms 
* Ephemeral configuration should be present
* Ephemeral or static db commit is performed


Solution

Please get the fix of PR1847834. There is no workaround.
