failed to import data from redmine to jira

[Irina Fridlyand]

failed to import data from redmine  jira-core jira jira-administration >java.lang.OutOfMemoryError: Java heap space That's a classic - it really does mean what it's says, the system has run out of memory.  Two possible approaches - give it more memory (change the value for JVM_MAXIMUM_MEMORY in setenv.sh), or try to import less data in one go.

In reply to Irina Fridlyand I was executing data import from redmine using redmine export pluggin.  I was exporting data for 6 projects, with dependency between projects.  The process was running for over 4 hours, when suddenly, got the following error in the log:  2017-01-03 17:23:38,975 INFO - Import started by irinaf using com.atlassian.jira.plugins.importer.redmine.RedmineDataBean 2017-01-03 17:23:38,984 INFO - ------------------------------ 2017-01-03 17:23:38,985 INFO - Importing: Users 2017-01-03 17:23:38,985 INFO - ------------------------------ 2017-01-03 17:23:38,985 INFO - Only new items will be imported 2017-01-03 21:18:00,257 ERROR - Unexpected failure occurred. Importer will stop immediately. Data may be in an unstable state java.lang.OutOfMemoryError: Java heap space 2017-01-03 21:26:00,349 INFO - No issues need to be reindexed. This is not very informational in diagnosing the problem.  Any recommendations?

in response to this we increased memory, and after 6 hours of processing I received the error that's attached: jira_import_error.jpg

these are a few lines from the log:

even though the error msg states no issues were imported, out of 6 project 1 was imported. 

Please aedvise.  The error is not really meaningful, sounds more like normal exception handling.

I accidentally deleted original ticket by accident. 

I have 35000 issues to import across 6 project.  I'd like to import all of them simultaneous to preserve cross dependency.

I'm not sure why you deleted the original question it had better information on it if memory serves.

I have to question the volume of data you are importing, how much have you got in Redmine?  The last time I did a Redmine import, it was a few minutes for thousands of issues, so 6 hours seems like it might be a massive import.  If it's not massive, then there's something else iffy in there chewing up the process.
