[tei-council] Roma returns error: unable to create new native thread

[Hugh Cayless]

An OutOfMemoryError definitely indicates restarting whatever process is issuing it. Depending on whether that process is running under Tomcat or not, restarting Tomcat may or may not help. Some things may still work, but whether stuff works or not will essentially be random. I got one generating a DTD.

In essence it’s a Bad Thing :-)
