Logs are generally the best option if you are using the downloadable version of JIRA. You log files will be stored in the JIRA home folder. Typically this would be /var/atlassian/JIRA on a unix system. If you don't have access to these or are using the on-demand system your best bet is to raise this directly to Atlassian them selves via their support protal.
It's also worth checking the "create" step of you workflows. Go into Administration -> workflows choose your workflow and edit. Once in click on the first status in the workflow (that is when an issue is created, the status it will be, not necessarily the first in the list). You'll see the create transition there and can look at it's conditions and post functions to see if anything might be preventing the creation of issues.
