Hi
Here is some more on that EAGAIN error;
access("/opt/jffnms/rrd/interface-11379-8.rrd", F_OK) = 0
write(6, "update \'/opt/jffnms/rrd/interfac"..., 57) = 57
fcntl64(7, F_GETFL) = 0x800 (flags O_RDONLY|O_NONBLOCK)
fcntl64(7, F_SETFL, O_RDONLY|O_NONBLOCK) = 0
nanosleep({0, 10000}, NULL) = 0
read(7, 0x8992f9c, 8192) = -1 EAGAIN (Resource temporarily
unavailable)
nanosleep({0, 10000}, NULL) = 0
read(7, 0x8992f9c, 8192) = -1 EAGAIN (Resource temporarily
unavailable)
nanosleep({0, 10000}, NULL) = 0
read(7, 0x8992f9c, 8192) = -1 EAGAIN (Resource temporarily
unavailable)
nanosleep({0, 10000}, NULL) = 0
read(7, 0x8992f9c, 8192) = -1 EAGAIN (Resource temporarily
unavailable)
nanosleep({0, 10000}, NULL) = 0
read(7, 0x8992f9c, 8192) = -1 EAGAIN (Resource temporarily
unavailable)
nanosleep({0, 10000}, NULL) = 0
read(7, 0x8992f9c, 8192) = -1 EAGAIN (Resource temporarily
unavailable)
nanosleep({0, 10000}, NULL) = 0
read(7, 0x8992f9c, 8192) = -1 EAGAIN (Resource temporarily
unavailable)
nanosleep({0, 10000}, NULL) = 0
read(7, "OK u:0.71 s:1.00 r:1869.04\n", 8192) = 27
nanosleep({0, 10000}, NULL) = 0
read(7, 0x8992f9c, 8192) = -1 EAGAIN (Resource temporarily
unavailable)
access("/opt/jffnms/rrd/interface-11379-4.rrd", F_OK) = 0
gettimeofday({1205346395, 943141}, {240, 0}) = 0
time(NULL) = 1205346395
time(NULL) = 1205346395
write(1, ".", 1) = 1
Here is the output of that other command I was asked to run;
[EMAIL PROTECTED]:~# ls -l /proc/3422/fd/7
lr-x------ 1 jffnms jffnms 64 2008-03-12 14:27 /proc/3422/fd/7 ->

Does that look right? Thanks
