Title: Netxmsd 1.2.13. Segmentation fault
Post by: smartdoc on April 08, 2014, 10:16:37 AM
Здравствуйте.

После обновления на версию 1.2.13 стал наблюдать падения сервера netxmsd связанные с segmentation fault.
Сделал core файл и привожу сюда backtrace. Надеюсь эта информация окажется полезной:
Code Select
Core was generated by `/usr/bin/netxmsd -D3'.
Program terminated with signal 11, Segmentation fault.

Хочется также упомянуть о записи в логи в кодировке без поддержки русских символов:

Как все это можно победить?

Don't understand any of this, but I have also had segmentation fault with the latest release.

Current workaround is an ugly hourly check.


#!/bin/bash
ps cax | grep netxmsd > /dev/null
if [ $? -eq 0 ]; then
  echo "Process is running." >> /var/log/netxms
else
  echo "Process is not running. Attempting restart" >> /var/log/netxms
  /etc/init.d/netxmsd start
fi

Это не "победить", а всего лишь временное решение....

В nxmc кириллические имена нод нормально отображаются?
Какая локаль на сервере?
Добален ли CodePage=CP-1251 в /etc/netxmsd.conf ?

Сервер собран из исходников или поставлен из пакета? У меня есть подозрение на то, что использование gethostbyname при нескольких потоках может вызвать такой эффект. Если собран из исходников, то я могу выложить патч для проверки.

Попробуйте заменить src/libnetxms/tools.cpp на приложенный и пересобрать.

после подмены, make отваливается с ошибкой:

Это можно проигнорировать. Достаточно из src/libnetxms сделать make install.

Отвечу за smartdoc. Сервер установлен из пакетов на систему Debian Wheezy. Если есть патч, по устранению падений, то не могли бы вы выложить собранный пакет под Debian x86_64? Локаль на сервере ru_RU.UTF-8. CodePage=CP-1251 в /etc/netxmsd.conf не был добавлен. Добавление CodePage никак не решило проблему (CP-1251, UTF-8). В панели управления имена отображаются нормально. Проблема только при выводе в консоль. Консоль - Putty, "Remote character set" - UTF-8. В консоль прикрасно выводится текст с русскими символами из файла в кодировке UTF-8.

Если это как-то поможет, то для обнаружения машин используются их dns name т.к. ip адреса машины полчают динамически и они могут меняться.

raypetter: Now I use a similar script in Сron :(

First, I am sorry for writing in English. I do not understand any of this, but today I upgraded to 1.2.13 and got the same error "Segmentation fault". The server runs for couple of minutes and then I get this error. Any known way to fix this?

As I understand, developers working against this bug.
For the moment you can downgrade or compile from sources with patch file.

2 vgourov:
1. get and unpack new package (1.2.13)
2. run ./configure with needed paramert
3. run make and make install
4. after installation, copy new file tools.cpp (https://www.netxms.org/forum/oe-oo/netxmsd-1-2-13-segmentation-fault/?action=dlattach;attach=1696) to src/libnetxms
5. run make install in src/libnetxms

2 vgourov:
1. get and unpack new package (1.2.13)
2. run ./configure with needed paramert
3. run make and make install
4. after installation, copy new file tools.cpp (https://www.netxms.org/forum/oe-oo/netxmsd-1-2-13-segmentation-fault/?action=dlattach;attach=1696) to src/libnetxms
5. run make install in src/libnetxms

I think that step 4 should be done before step 3 (make && make install) in order to apply changes in source file. Command make install only copies compiled files to proper locations.
