-====== Troubleshooting ======
-{{indexmenu_n>50}}
-====== 1. The instruction "service fastdpi reload" does not work ======
-This instruction loads "hot" parameters without service restart:
-<code>
-service fastdpi reload
-</code>
-If this instruction is absent, the following instruction gives the similar effect:
-<code>
-kill -HUP 555
-here 555 - is PID of the fastdpi process
-</code>
-However it is better to [[en:dpi:update:previous:ver_1_0:start|update DPI to version 1.0]].
-====== 2. Utilities url2dic and ip2bin are absent ======
-{{indexmenu_n>2}}
-Install utilities by the instruction: <code>yum install dpiutils</code>
-"Vasexperts" repository must be attached if required:
-<code>
-rpm --import http://vasexperts.ru/centos/RPM-GPG-KEY-vasexperts.ru
-rpm -Uvh http://vasexperts.ru/centos/6/x86_64/vasexperts-repo-1-0.noarch.rpm
-</code>
-====== 3. The network driver can not be loaded after the kernel's update ======
-{{indexmenu_n>3}}
-. In case your network driver can not be loaded after the kernel's update, you can try to resolve the issue by yourself:
-<code>
-ls /lib/modules/`uname -r`/extra
-</code>
-If kernel modules pf_ring.ko and igb.ko (or ixgbe.ko for 10G cards) are not present in this directory, please copy them from the similar directory of the previous kernel version: <code>find /lib/modules -name pf_ring.ko
-cd path_found
-cp pf_ring.ko /lib/modules/`uname -r`/extra
-cp igb.ko /lib/modules/`uname -r`/extra # or ixgbe</code> and execute these instructions:
-<code>
-depmod -a
-modprobe pf_ring
-modprobe igb # or modprobe ixgbe
-</code>
-. If your network card supports bypass functionality: you need to recover the bypass driver as well.
-To find the driver:
-<code>
-find /lib/modules -name bpctl_mod\*
-</code>
-Copy it to extra:
-<code>
-cp bpctl_mod.ko /lib/modules/`uname -r`/extra
-depmod -a
-</code>
-To verify operation:
-<code>
-bpctl_start
-bpctl_util all get_bypass
-</code>
-Please contact tech support if these steps do not help.
