gam_server, Solaris and high CPU load

Since upgrading to s11b83a I noticed that gam_server processes eat significant amount of CPU cycles. So I decided to make some investigations.

# uname -a
SunOS xeon 5.11 snv_83 i86pc i386 i86pc
# pkginfo -l SUNWgamin
PKGINST:  SUNWgamin
NAME:  Library providing the FAM File Alteration Monitor API
CATEGORY:  GNOME2,application,JDS4

No manuals, no config files.

# strings  /usr/lib/gam_server
. . .
/.gaminrc
/etc/gamin/mandatory_gaminrc
/etc/gamin/gaminrc

From Gamin project page:

Gamin is a file and directory monitoring system defined to be a subset of the FAM (File Alteration Monitor) system. This is a service provided by a library which allows to detect when a file or a directory has been modified.

This is the description of the config file: Gamin config

Now, how to fix the problem

Create /etc/gamin directory:
```
# mkdir /etc/gamin
```
Create file /etc/gamin/gaminrc. It may contain the following lines (this is just an example, you can set your own polling intervals):
```
fsset nfs poll 15
fsset ufs poll 15
fsset lofs poll 15
fsset zfs poll 15
```
Restart gam_server (let me know if there is a better way):
```
# pkill  gam_server;  rm -rf /tmp/gam_*
```

Voila! That should be done in all zones.

Update 2008-07-07 @00:06:24: i did not see this behaviour in snv_92. However, do not install snv_92 because of otehr bugs. Try snv_93.

Unlocking pkgadd

## Waiting for up to <300> seconds for package administration
commands to become available (another user is administering 
packages on zone <XXX>)

Remove /tmp/.ai.pkg.zone.lock-* from all zones
Remove /var/sadm/install/.lockfile
Remove /var/sadm/install/.pkg.lock (<- not sure about this one)

How to compile wine under Solaris. Part I

Unfortunately, wine can not be compiled under Solaris “as is”. Some tricks are needed.

./configure --without-ldap --disable-win16

To get rid of the following error:

Compile with /usr/sfw/bin/gcc not /opt/csw/bin/gcc. You can successfully compile wine with CSWgcc but if you run wine or winecfg you will get the following error (at least under Solaris 11 builds83a-86):
```
$ winecfg
sock_init: ERROR in sock_check_pollhup()
Assertion failed: next->flags & VFLAG_SYSTEM, file virtual.c, line 467
Abort
```
