Since several packages link dynamically to this library you are advised to restart the corresponding services or programs respectively. The command 'apt-cache showpkg libpcre3' will list the corresponding packages in the 'Reverse Depends:' section.

For the old stable distribution (woody) this problem has been fixed in version 3.4-1.1woody1.

For the stable distribution (sarge) this problem has been fixed in version 4.5-1.2sarge1.

For the unstable distribution (sid) this problem has been fixed in version 6.3-1.

We recommend that you upgrade your libpcre3 package.");
