Hi Luz Rodriguez,
Dump tran command is fired distributed checkpoint for each node
and then it can be processing continuously after recieving successful message from remote node.
Please check both nodes to have an incompleted transaction.
select * from master..syslogshold
go
And if there is no one, run checkpoint command for each node and then try to run dump tran command.
Please check ASE CE User's Guilde(SyBooks Online) for distributed checkpoint.
Thanks,
Jongun Seo
