Problem about NEB interruption

[leon_qian]

Dear Sir,
Here is another question. Sometimes, my NEB would interrupt after several steps, and the error message is:

rm_l_2_7375: p4_error: interrupt SIGx: 15
rm_l_2_7375: (2015.175781) net_send: could not write to fd=5, errno = 32
bm_list_7370: p4_error: interrupt SIGx: 15
rm_l_1_7374: p4_error: interrupt SIGx: 15
rm_l_1_7374: (2015.691406) net_send: could not write to fd=5, errno = 32

After resubmission, sometimes, the job can continue, but sometimes, it quits after only one step.
What is wrong with it? How to solve this problem?
Many many thanks!
