What does this unexpected EOF error means?

[Michael Angelo Timoteo]

Hi guys, when I am checking out atlassian-jira.log, I always encounter this  Uncaught exception thrown by REST service: Unexpected EOF read on the socket
java.io.EOFException: Unexpected EOF read on the socket. 

Is this causing jira slowness?

How do I prevent this?

Hello Michael,

Checking other customer reports about this error, I could found out that it is usually related to a failure when uploading attachments to JIRA issues, but I could not find anything related to Slowness because of this error.

This failure can be caused by several reasons as connectivity problems or even because of Storage Space, so a further investigation will need to be performed to identify the root cause of the problem itself.

That being said, have you heard any complaining about files not being uploaded to your JIRA?

If you identify someone which is not being able to upload files to JIRA, I recommend you to open a ticket with our Support team providing the browser, the file (If it is happening only to a specific one) and the frequency that it's happening.
