Hi,

on one of the computers I manage, I have seamonkey mail writing data
continuously on the NFS storage.

nethogs shows:
TID  PRIO  USER     DISK READ  DISK WRITE  SWAPIN     IO> COMMAND
8639  be/4  guillaud    0.00 B/s    21.56 M/s    0.00 % 38.51 %
seamonkey -mail

and iftop confirms the io continuously.

I've setup seamonkey to consult the mail server only every 5 mn and
disabled automatic folder compression.
But no change....
Seamonkey is seamonkey-2.21-4.ESR_24.3.0.el6.x86_64.

Thanks for your advices.

Patrick

Patrick, Why did you turn off automatic folder compression?? In doing so, you have set yourself up for creating a huge inbox folder which will be looking for more and more space on your HD.
Hi Daniel,

Yes, I know this but I would like to understand what is this continuous disk access. So I've disabled this automatic compression at this time.

Try File->Empty Trash then File->Compact Folders and see what happens.

This doesn't solve the problem. Since yesterday, I've worked on this problem but still no solution.
That I know now is:
- The file concerned by this continous write is .mozilla/seamonkey/aw16q4e9.default/addons.sqlite-journal
- Seamonkey-mail write nearly 10 Mbytes/s in this file.
- the content of the file must be overwriten, as its size doesnt grow.
- a strings command on the file show mainly ocurences of "https://addons.cdn.mozilla.net/img/uploads/previews/.../xxx.png"; URLs.

I've restarted seamonkey with all plugin disabled but it doesn't change and moreover seamonkey seam to hang now when asking again for this page (about:addons).

As the home is a NFS storage, this client generate an average network load of 100Mbits/s continuously

Patrick



Have a look here:

Could be two users running Firefox and accessing your nfs storage locks passing from one to the other ....
