CCL: Problem with IRC Convergence

 Sent to CCL by: "Matthew  Tassell" [mtassell{}gmail.com]
 Dear CCL
 I have been having problems trying to get an IRC calculation to work and i have
 tried everything that i know about to solve the problem. Below is the data from
 the first step away from a transition state.
  IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC
  Pt  1 Step number   1 out of a maximum of  60
  Using modified Bulirsch-Stoer corrector interation.
    Using distance weighted interpolants to fit PES.
     Cycle     1 NS=     2
     Cycle     2 NS=     4 Truncation Error =  0.001789004
     Cycle     3 NS=     6 Truncation Error =  0.000008665
     Cycle     4 NS=     8 Truncation Error =  0.000005185
     Cycle     5 NS=    12 Truncation Error =  0.000001043
     Cycle     6 NS=    16 Truncation Error =  0.000000149
     Cycle     7 NS=    24 Truncation Error =  0.000000054
     Cycle     8 NS=    32 Truncation Error =  0.000000007
  BS completed in    8 cycles and     104 integration steps.
  SUMMARY OF CORRECTOR INTEGRATION:
    Original End Point Energy  = -1661.292015
    Corrected End Point Energy = -1661.292096
    Old End-Start Dist.        =     0.029095
    New End-Start Dist.        =     0.000011
    New End-Old End Dist.      =     0.029095
  CORRECTOR INTEGRATION CONVERGENCE:
    Recorrection delta-x convergence threshold:    0.001826
    Delta-x Convergence NOT Met
  IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC-IRC
 and this is the route section from my job
 %NProcshared=4
 %MEM=3000MB
 #p irc=(MaxCycle=60,stepsize=1,tight,rcfc) M062X/6-311++G** scf=maxcyc=200
 scrf=pcm guess=read geom=check
 I have tried playing around with the step size and convergence criteria to try
 and get a feel for nature of the TS but what ever i seem to do leads to the same
 error message, Delta-x Convergence NOT Met.
 If there is anybody who might like to offer a suggestion as to what is the
 problem i would be very gratefull
 Many thanks in advance
