 I have 641 ports installed.

 I deleted all the inactive ports.

 I then ran a command to force upgrade them all with the +universal
 variant:

 script bigbuild.log sudo port -pdk upgrade --force installed  +universal

 After a few hours of compilation an error occurred:

 ./libtool: cannot make pipe for command substitution: Too many open files

 I increased the ulimit(1) open files limit for the process from 256 to
 10000
 and ran the upgrade command again.  While it was running I monitored the
 open files for the tclsh process using lsof:

 I noticed that there were a lot of instances of

 /opt/local/var/macports/receipts/file_map.db

 open.

 I counted them with:

 sudo lsof | grep -i tcl | grep receipts | wc -l

 and there were 272 instances of this file open.

 I think there is an open file leak in port.
