TinyMUSH 3.1 Crashing After a Power Outage

A CentOS Linux system on which I was running TinyMUSH 3.1 patchlevel 5, the latest version of the MUSH available at the time I'm writing this entry, would not restart after I brought the system back online after a power outage. When I ran the Startmush script, I would see the following:

The "line too long" messages are normal for this MUSH and don't impact the functioning of the MUSH. The first unexpected message I see is the line below:

*** glibc detected *** ./bin/netmush: double free or corruption (top): 0x000000000c2076f0 ***

The line in the Startmush file that was producing the error message is shown below:

$BIN/netmush $make_db -c $GAMENAME.conf -l $LOGNAME -p $PIDFILE -t $TEXT -b $BIN -d $DATA -g $GDBM_DB -k $CRASH_DB >>$LOGNAME 2>&1 &

I suspected the problem might be related to the fact that I'm running the MUSH on a 64-bit version of CentOS now. It was previously installed on a 32-bit Red Hat 9 Linux system. I remembered encountering problems when I initially moved it to the CentOS system in April, related to the fact that the CentOS system was a 64-bit operating system. Unfortunately, I can't remember exactly how I resolved the problems I encountered then.

When I performed a Google search on "glibc double free or corruption 64-bit", one of the pages I found, glibc detected double free or corruption error? had a posting by RavenOfOdin that offered a solution:

Re: glibc detected double free or corruption error?

That's an old Linux C++ error. Not new news.
To fix it so you can run the program just type:

export MALLOC_CHECK_=0

before running the program.

So I entered the command export MALLOC_CHECK_=0 from a BASH shell prompt before the Startmush command. It solved the problem and the MUSH started as before the crash. I don't remember entering that command previously to get the MUSH to run, but since it did fix the problem, I thought I had better document it for the next time I encountered the problem.

$ export MALLOC_CHECK_=0
$ ./Startmush

Ghost 2003 Backup of Laptop SATA Drive

I received another HP Compaq tc4400 laptop while mine, which would no longer power on, was being repaired. I put the 80 GB SATA drive from my laptop in the new laptop. I wanted to backup the drive to an external USB drive using Norton Ghost 2003 prior to using it in the new system, so I attached the laptop's external DVD drive and attempted to boot from a Ghost 2003 boot CD. I received a message that command.com couldn't be found. I tried several Ghost 2003 boot CD's, but none worked. I was able to boot from a Ghost 2003 boot floppy disk, but when I ran Ghost, I received the message below:

Application Error
Read sector failure, result=1, drive=1,sectors 729050177 to
729050178
If this problem persists, contact Symantec Technical Support
at http://service.symantec.com

I put the drive in a desktop system and booted that system from one of the Ghost 2003 CDs I had tried with the laptop. I didn't receive any error messages and was able to back up the drive without any problems, so I'm not sure why I received the error message when attempting the backup with the laptop.

I know that sometimes a CD or DVD drive will have problems with discs from a particular manufacturer, so perhaps the external HP DVD ROM drive (p/n: PA509A#ABA) was having a problem reading the Office Depot CD-R discs I had put Ghost on, but that shouldn't have any bearing on Ghost aborting when I tried to start it to backup the disk drive. I was able to boot the laptop using the external DVD-ROM drive with an Ubuntu Linux LiveCD.
