hi dear...

The problem you are mentioning should not arise as everything was working fine earlier and if u have not made any changes recently... However, I have one suggestion to u from my experience,, (although it isnot very pertinent to ur problem but generally it works), tht is, u upgrade version of JunOS firmware... whichever u r using rite now, better upgrade to latest stable firmware,, and hopefully u will find things geting better.. i wish it to work for u...

We have also ex2200 where we have packet-loss on the egress interface. Try this command to check

show interfaces queue [Interface]

 

If you see tail dropped packets you know where the problem is.

 

I've opened a ticket for JTAC and hope for an answer soon

Recommended release for the EX-2200 right now is 10.4r9. The "r" releases do fix a lot of issues. See http://kb.juniper.net/InfoCenter/index?page=content&id=KB21476&smlogin=true

 

A PR search on support.juniper.net shows 683 EX-Series issues tracked between 10.4r1 and 10.4r9. They won't all be relevant to you. Still, going to current recommended is a good idea. If you then still have the issue, definitely track with JTAC/ATAC.

 

You can also use rollback ? to see where changes have been made, and show | comp rollback X where "X" is the rollback number when things were still working, to see whether there was a config change after all that may have caused this.

Hi Nilsw,

 

We have a client experiencing this same issue with 10.4r1 - the entire routing-engine seems to lock up after a period of time and only a reboot will fix it.

 

We're going to try upgrading to 10.4r9 and see if it resolves the issue.
