[Dovecot] sendfile on Solaris 10 SPARC?

[Tan Shao Yi]

Hi,

I am using dovecot-1.0.2 and am observing occassions where the imap 
process for the user goes into an infinite loop.

A truss of the process gives:

pollsys(0x000B0308, 4, 0xFFBFF898, 0x00000000)  = 1
fstat64(10, 0x000BC130)                         = 0
sendfilev64(1, 1, 0xFFBFF4B0, 1, 0xFFBFF4A4)    Err#11 EAGAIN
pollsys(0x000B0308, 4, 0xFFBFF898, 0x00000000)  = 1
fstat64(10, 0x000BC130)                         = 0
sendfilev64(1, 1, 0xFFBFF4B0, 1, 0xFFBFF4A4)    Err#11 EAGAIN
pollsys(0x000B0308, 4, 0xFFBFF898, 0x00000000)  = 1
fstat64(10, 0x000BC130)                         = 0

(... repeatedly ...)

When I searched the maillog for the user, the last actions taken were:

May I know what could have caused the problem or is there any 
other information I can provide?

Thanking in advance.
