+The network support "|&" may not work under HP-UX 11.
+An error message appears similar to this:
+gawk: test_script.awk:3: fatal: get_a_record: iop->buf: can't allocate -61246
+bytes of memory (not enough space)
+
+Solution:
+This is a bug in the fstat() call of HP-UX 11.00, please apply
+the cumulative ARPA Transport patch PHNE_26771 to fix it.
+
+The following is the related description in PHNE_26771:
+
+	Customer's application gets the wrong value from fstat().
+        Resolution:
+        The value returned via st_blksize is now retrieved
+        from the same info as in 10.20.
+
+In case you cannot apply the HP patch, the attached patch to gawk source
+might work.
