We get this kind of an error intermittently. Does anyone know what would cause this? Any idea what error code "-7" is?

com.atomikos.datasource.ResourceException: resume for XID 172.26.33.33.tm0379000029172.26.33.33.tm3026 raised -7: the XA resource has become unavailable
        at com.atomikos.datasource.xa.XAResourceTransaction.resume(Unknown Source)
        at com.atomikos.datasource.xa.session.BranchEnlistedStateHandler.<init>(Unknown Source)
        at com.atomikos.datasource.xa.session.NotInBranchStateHandler.checkEnlistBeforeUse(Unknown Source)

It means: "the resource has become unavailable".

Probably your connection has intermittent problems?

BTW: you may want to define a testQuery on the datasource, so this can be detected and caught early.
