Delayed write errors

[Sanghvi, Arun R. (GE Power)]

Hello

Under heavy I/O load we are getting delayed write errors
Description:

Log Name: System
Source: Mup
Date: 5/19/2016 12:09:37 PM
Event ID: 139
Task Category: None
{Delayed Write Failed} Windows was unable to save all the data for the file \\isilon.gene.psec.ge.com\eng\LOCA\guangj\201 ---; the data has been lost.
This error may be caused by network connectivity issues. Please try to save this file elsewhere.
Event Xml:
<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event

Any suggestions on how to resolve this issue?

Should we consider changing SMB timeouts described at

Thanks.

Hello,

We are currently experiencing the same problem.

{Delayed Write Failed} Windows was unable to save all the data for the file \\islXXXXXfls01\XXXXX\XXXX_XXXXXX_XXXXX\$XXX\$XXXX\XX-XX-XX XX-XX-XX AM\job.mdb; the data has been lost.

This error may be caused by network connectivity issues. Please try to save this file elsewhere.

Is this related or could the cause be the Timeout on SMB


Any suggestions?

Thanks

Please not that we resolved this issue .

 

Root cause:

ISILON was behind a firewall.  Firewall could not keep up with heavy I/O load

From  24 servers running  400+  EXE.

 

Solution:

Move ISILON outside the firewall.
