Snapcreator 4.1P1: Error after successful execution of all SnapVault updates in configurations with multiple controllers

ANDRIANAIVO

Hi,

We are having an issue in Snapcreator Version 4.1.P1 with configurations that use snapvault updates and where we have more 2 or more controllers as Snapvault source.

SC-Server:

--

SW-Version: 4.1P1

Java-Version: 1.6.0_24

OS-Version: CentOS 6.2

--

SC-Client:

--

SW-Version: 4.1P1

Java-Version: 1.7.0_55

OS-Version: RHEL 5.8

--

Snapvault settings from the configuration file

--

NTAP_SNAPVAULT_UPDATE=Y

SNAPVAULT_QTREE_INCLUDE=

NTAP_SNAPVAULT_NODELETE=N

NTAP_SNAPVAULT_RESTORE_WAIT=N

NTAP_SNAPVAULT_RETENTION_AGE=

NTAP_SNAPVAULT_SNAPSHOT=N

NTAP_SNAPVAULT_MAX_TRANSFER=

NTAP_SNAPVAULT_WAIT=1440

NTAP_SNAPVAULT_RETENTIONS=DAILY:8

SNAPVAULT_VOLUMES=siss-naa01b.spar.si:L_CLCACH_VG_CACHE_CEN,L_CLCACH_02;siss-naa01a.spar.si:L_CLCACH_01

The Error message we got in the logs are:

Did someone else have a similar issue or even a workaround for this problem?

The issue does not occur on every run. I think, it may be a problem with transaction/session

handling, which behaviour has changed in hibernate 4.

I would appreciate any inputs

Update: currently this was a ressource allocation issues. The Follwing changes solved our Problem:

1. increase limits for open files on the SC Server

2. increase amount of physical RAM on the SC Server
