I'm not able to reproduce your problem on either 4.3 RELEASE or current 4.3-STABLE. On both of these I get: $ ./sockin 4711 ./sockin: 127.0.0.1 close (which I assume is the correct behaviour). Could you give me more information to allow me to debug your problem? Thanks. /assar State Changed From-To: open->feedback tried on 4.3 and 4.3-stable and send back mail to submitter for more details On 16 Jun 2001, Assar Westerlund wrote: > I'm not able to reproduce your problem on either 4.3 RELEASE or > current 4.3-STABLE.

A program sets up a socket to listen to and waits for incoming connections in select. A second program calls connect which is fairly often not detected. How-To-Repeat: Run these two programs on the same 4.3 machine. begin 644 two.tgz M'XL(`"<"'#L``^U7?T_C1A#E7_M3#*E([5,`._Q2+U`I*CDU*@VG!*[J<2?+ MV!MB7;*.O&LHK?CNG=FUDS@$N-,=M%7WG<YV9F??SHQGUP^11I\2OA6M/2-\ MS]O?W84U`/]@SZ<[PBON`#M-WP,XV/'V]GS?:_KHYN\T]]?`>\Z@2N1"AAG` MVC1+F90/^]V,&!N_1$`OB^\2'HWSF%F'0L9)NC7ZT9Z;<IZ@M6KC3,:7:((% MF[@5V_)VRD3559F3";MO%=AU3-XC3O#_-G9CQ1YFTW";1LAL3\*$.V%V%34` MK]>NG7!IT>^6'8W"S'I%UHN/+?LOVZ*A8=P`3I<QXPU(\$<#IFDF6[:E_"_S MX<6N]\,^SK"$S/)(6A1<&,=9D'!+T`,.#>-`,!QB8[PU(&-AC`_S.93F=3A6 M]S3'`5Q]""I06#^"I@L8CS6<9AC3T,&BLBQK0"T7X15[#1M"Q<3SR0=>TXE= M>!]=I+?8'XET?'J\*SB=80Q'H"OHM-\$W5[GK`&#TY]^"09G_4[[UP9XK@N' M>%6+3G&I-'-J>D9M%2OR^90+D^243J5#%1N<G@1$J^F#?N=\T&D?'_<;X%#I MX)5;QWJ*Y$^6#IW$=2EI2@/90IDFCDK#5VFH,FZ)A`?D<`0CF7+A.#D7R15G M,8@1FET:JWKK!W5#UFZ/E@_:O=\K3L-PDHQO<;PH1DO7Z3+AL<K#T>\(RO=* M@:O9L^#5KU4U(PZLF(6F:)P*AGP/O)4Q[A3&U7J[+AP=P:9?I=(.NOR/<!4- MM"6O@URP"+/R6A6K-OH>5?O-<?"^TS]UZD4_$@G:!ITS%<B"&3LXS<!IM710 MNH^19][(%J>N8F,624=S#+KO.TA2]GSO_.2DO-:+@%0"E#Y?3'G><HI.YVQ% M*<<-GC/Z<;<XS2MGZ<U1*[@_\$<FKF.(W<$L41VCNT2D.QYX*HO$6+S^`"M> M\("@"BQVA"J+VFYA%+%B6SS23G7DF)>$)JXHBJ9Z(+<R]`U!I\+B:8"'%YZ!
