@Las Vegas

只在HP UX 发生的奇怪问题,那位给个建议?

mike20030405(mike)
运行
curl -v -0 http://www.google.ca
* About to connect() to www.google.ca:80
Pid 15602 received a SIGSEGV for stack growth failure.
Possible causes: insufficient memory or swap space,
or stack size exceeded maxssiz.
Segmentation fault (core dumped)

环境是
HP-UX Pender B.11.11 U 9000/785 2016223922 unlimited-user license

在windows 和solaris执行都很正常,只在HP上才发生,而且没有好的解决方法.

网上搜到的解决方法一般有两种:
1. 去掉补丁PHCO_26124. 我用swlist没有看到这个补丁,swremove也没找到此补丁;
2. 修改核心参数maxssiz. 此方式需要编译内核.这台机子数据很多,不太敢下手(是否是在/etc/conf/master.d/core-hpux修改).

几个问题请教:
1. 那里可以找到UX 11.11的最新补丁集?
2. 编译内核危险吗?别搞死了恢复不了就麻烦了.
3. 那位达人碰到过此问题并且有解决方案?

非常感谢!

      1. 那里可以找到UX 11.11的最新补丁集?
      在www.itrc.hp.com里面下载，需要注册

      2. 编译内核危险吗?别搞死了恢复不了就麻烦了.
      用sam来做比较保险。做之前先用tape做一个make_tape_recovery就不用怕

      3. 那位达人碰到过此问题并且有解决方案?
      你有root吗？跑个vgscan看看？还有swapinfo，如果有glance，再跑个glance -m
      • 1. 已经注册，明天下载安装后再来汇报（是否下载最近的一个版本就可以？）。 2. 没有tape。能否做一个象ghost那样的镜像做备份？ 3. 没有glance. 哪里有免费的下载？其他状态明天奉上。 非常感谢。有什么建议请不吝赐教。 -mike20030405(mike); 2005-11-30 (#2635601@0)
        • 1. yes. 2. no. 3. free的试用版在software.hp.com有，用glance做关键字搜索 -pasu(InTheSky); 2005-11-30 (#2636430@0)

        • c0t0d0应该关系不大。你strings -a /etc/lvmtab看看它在不在？还有ioscan -fnCdisk，看看在不在，是不是NO_HW。还没看见你的swapinfo output -pasu(InTheSky); 2005-11-30 (#2636434@0)
      • 非常感谢,已经解决.其实是软件包未装全呼,重装了openssl,libicon,zlib,libidn,curl等一堆东西后就okay了.总之,非常感谢,以后还要多请教. -mike20030405(mike); 2005-12-1 (#2638315@0)
